Just a bit of info: You don't need the specialty tool. You can use a 1/2" [6sided] Ratchet-Alan. This is info from a Merc engine mechanic near me, and I also did it. Worked fine. Edit: He also told me he has broken those tools several times. And he has yet to break an alan or bolt. :-)

executive chef and boat mechanic! Great job sir

[@gatorsaw3315]

Glad to see you did not use the dumb block of wood method removing the drive. 25 years as a boat mech and i cant say I saw anything done wrong here,, Nice wrk..

I’m glad I found this video. I thought maybe I could change an engine on an old boat but it looks to tough for me. You made it look easy but you won’t be here

[@ChefOutdoors]

I’m glad you liked the video. It is a big project. I hope this helped give you an idea of what you would need to do it and how you might do it if you try. Please let me know how it works out

[@jamesblack5223]

It's not that bad it's time and uncomfortable while unhooking water lines and wiring but really not as bad as you would think.

About to replace my old 470 with a reman 470 Mercruiser in my boat so this is very helpful. Alpha 1 Gen 1, not sure the difference between the Gen 1 and 2?

[@gl3826]

Great video. ("Footnote", Kingston ON)

[@ChefOutdoors]

Thank you

[@tomtamshen7277]

I really enjoyed your video, can't speak to that enough. I have a 1994 Bayliner with a 454. Do I have to remove the outdrive to replace the engine? I did not see how you lifted the motor, any advice? Might it be better for me working outside to remove everything I can off motor to reduce weight or is it better to pull all to reassemble to a new motor? I bought boat at auction and it had 9 gallons of clear water in oil pan.

[@fizzybillylah3816]

Yes. You need to remove outdrive in order to remove engine. And I recommend you buy a complete turn motor replacement or you’ll be doing this job again…that’s experience talking!! I pulled an old engine from my boat patched it up with new gaskets and starter and alternator and then did ran descale through engine passages. All for not…engine still overheated and likely blew a head gasket. It’s expensive but I recommend a complete turn key engine replacement. I had a tow truck come lift my engine out. Tow truck has to have a boom that goes high enough into air and is not connected to its under car carrying boom

[@nathanalandt615]

I heard you mention that this is a Gen II Alpha 1. Why do you have an extra raw water pump? My understanding is the Gen II's can handle a full closed cooling system with just the outdrive pump and the engine circulating pump? I am looking at doing a project similar to this and planning on adding a heat exchanger to it.

[@imbranjamil4994]

The best

[@jamesblack5223]

I had to make my specialty tool. I Currently have engine ready to pull the see what my options are for a cracked block fix or swap or swap then fix. What's more important time or money? I say time however time goes well with a couple buddy's and so.e beers and some wrenching while trying something new.

[@camaroiowaguy23]

was focused on the starter portion. i have the same motor in an 86 larson delta cruiser. however i only got 1 bolt out and the inside bolt is real hard to reach. was trying to see if i can undo the 2 front motor mounts to lift an inch or 2 or not. not wantin to do this whole process. ugh

[@AchikSarih]

Merci beaucoup ❤❤❤❤❤

[@KenStinnett]

that tool is called a triple square. most German car mechanics have these. thanks for the video , going to tear out the 1987 Chris craft i just bought

[@ChefOutdoors]

Sounds like a fun project!! Thank you for watching. A triple square🤷‍♂️ learn something new every day

[@kenmorison6464]

Editing makes it look soooo easy, LOL

[@ChefOutdoors]

for sure! lots of video to chop down.. its not too bad once you do a couple. practice makes perfect.

[@alexhayes7588]

Does your starter require a 90amp fuse for the solenoid? The battery was hooked up backwards on for my mercruiser 350 and it tripped the breaker on the motor, but there's no fuse on the solenoid and I think it trashed the starter.

[@ChefOutdoors]

People and manufacturers put them on some of them. It is not required but probably a good idea. Electrical with anything can be tricky and Cost a lot of money ruining things if hooked up wrong. I would advise you to follow what the manufacturer states is recommended for your particular engine.

[@davodavico]

Great job! I am planning to get a 1977 Mercury Marquise. Engine: Mercruiser 4788052. The body of the boat looks impecable; however, the owner told the seal between the engine and the outside part might need to be replaced. Any ideas, suggestions on this, please? How advisable for me it is to buy something like this? I am a new comer and has zero knowledge on boats. Thank you!

[@ChefOutdoors]

For having zero knowledge on boats this is a very time consuming job that requires knowledge particular to each engine configuration. You are going to pay a mechanic good money to do this. So make sure you take that into consideration before making a purchase. It will probably be very costly to pay for this work. It will be a big project for you to learn and do yourself. Good luck. Boating is a great fun time, but definitely a costly one.

[@bayoutrapper3782]

If be says that seal is bad I would be suspicious of transom rot. As Chef said it's expensive, a labor of love. I talked to reputable marine mechanic he quoted me at least $2500-$2700 to change engine coupler, pump, and lower unit oil. I have the original mercruiser manual, watched a few videos, and did it myself in a weekend. Saved about $2000. It's not hard but it is work, you'll probably need a friend to help. Hope this helps somebody. God bless.

[@DavidJohnson-cv6hn]

That special tool looks like its just a triple square

[@MenCanNotBeWomen]

should have put dielectric grease on them postive cables connection to the starter motor, so they wont rust up etc

[@ChefOutdoors]

agreed! great tip! thank you for sharing.

[@mikedodd9294]

man do i want steel toed boots after watching the engine going down

[@jeffasselin829]

Sounds good. Now let's get some fish

[@ChefOutdoors]

For sure!! Time to get to it😁

hope ya put sealant inside the holes the bolts are in

[@ChefOutdoors]

for sure! thanks for adding great tips for others to see!

Скажите пожалуйста. Где купить редуктор на Меркури 260

[@dumpa123]

Awesome video! How many hours did u guys spend on doing this job ? i´m about to do the exact same procedure this week..

[@ChefOutdoors]

Engine out about an hour Drive off about 20 min Transom assembly removal was around an hour Transom assembly install was probably another hour Engine install was around 1-1/2 hours to get it in and accessories attached Out drive reinstall was about 30 minutes We broke it up over a couple days after work

[@jonathanjohnson8092]

I have a 1993 Crownline 193 br 19 ft speed boat it has a 5.0 L engine in it now with a cracked block will a 454 7.4 engine fit in my boat?

[@kbgking7921]

It won’t be a direct drop in replacement. Make sure your outdrive can handle a bbc

[@ChefOutdoors]

Every boat is different I do not know. Good luck with the project

[@ForestBunz]

I have the same boat! I'm thinking of a 350 swap (with slightly higher compression/cams and bigger/better carb) down the road as almost everything bolts up (manifolds and water pumps etc) and its basically the same size verses the 454 big block. Just don't want to overpower the drive unit...

[@douglashersom5128]

Wondering about how long it takes? I have a 4.3 I'm thinking about replacing.

[@ChefOutdoors]

it really depends on you. I can have an entire engine out in 45min-1hour and maybe a couple hours putting it back in if I have everything I need, but that is most normally not the case. something breaks or something is no good and needs replaced, or you don't have a tool or part you need and it turns into days. plus if you have a job then ya got to go to work and it takes even longer. you just never know. circumstance permitting

[@douglashersom5128]

@@ChefOutdoors I get that, spent two days last week hunting down the parts for my truck after advance sold me the wrong ones.. I'm really torn.. I have a chance to buy a 96 stingray 5.7;for 3k with a "new" motor two years ago but the boat is a mess, cluttered with crap.. or a 04 crownline with a 4.3 then tossed a rod but is clean as a whistle.. not crazy about doing a motor but at least with the crownline I know what I have.. 🤦

[@ryananey7626]

Great job sir. Do you have to take the outdrive off if you are only swapping out the engine? I gotta put a new 350 in my dads trophy. Thanks

[@ChefOutdoors]

Yes you do. the drive shaft or "donkey dick" as they call it. (not a joke) is splined into the engine coupler bolted to the flex plate. so yes you do have to remove the drive also before removing the engine.

[@ryananey7626]

@@ChefOutdoors great thank you for replying sir. Cheers!

[@ChefOutdoors]

thanks for watching!

[@makai335]

I have alpha 1 gen 1 outdrive, can I change it to bravo outdrive? Thank you

[@ChefOutdoors]

not without changing the transom assembly

[@mikehunntt5338]

I have Gen 2 outdrives would love to do the same

[@tristenfletcher577]

How much would it cost to remove a 3.0 volvo penta engine and put a 4.3 mercury engine in

[@ChefOutdoors]

all depends on who does the work and what has to be modified to make it work, drives, transom assembly, etc. not a cheap job

[@aubreyanderson9291]

Can I get the engine out without messing with the out drive?

[@ChefOutdoors]

No. You have to pull the splines out of the coupler. So you have to remove the drive to do that

[@anthonysiegel4685]

Why didn't you change the gamble bearing and boot

[@ChefOutdoors]

it all looked good at the time! so we didn't, but we are doing some work to it now and I am going to change them in a new video very soon.

[@deucedawg01]

what did you use to pull the engine out?

[@deucedawg01]

23:40 must be a forklift.

[@ChefOutdoors]

yes a for lift for this one. sometimes I use an A-frame with a chain fall also

[@roycewheat1897]

How do you disconnect the engine from flywheel?

[@ChefOutdoors]

You have to remove the bell housing then unbolt the coupler from the fly wheel or “flex plate” as it sometimes called. Then there is a series of bolts holding the fly wheel to the crank.

[@jeremypeloquin8214]

You guys look familiar... 😂

[@ChefOutdoors]

I am a familiar looking fellow😁

[@latrex]

Bravo fit on Alpha transom?

[@ChefOutdoors]

you would have to replace a lot to make it work correctly. the transom assembly is different and would need to be changed, different shift system and different water cooling supply.. I mean you could remove an alpha drive and transom assembly and replace it with a bravo drive and transom assembly, but there is also a lot to it and the engine and drive would need to be configured to make it all work correctly.. can't just swap them.

[@latrex]

@@ChefOutdoors I have Maxum 2300 sc 1999, inside was 5,7 car + alpha g2. I buy boat without engine and gear/transom. Just thinking now what put inside for small money

[@ChefOutdoors]

@@latrex gotcha.. it is quite the project.. alpha would definitely be a cheaper route. can't just put a car engine in either it has to have the right cam.. however the 5.7 EFI car engine was one of the only ones with the correct cam to do the job. sounds like your on the right track. let me know how it goes..

[@nickstockam3247]

How long did it take y'all to do this job?

[@ChefOutdoors]

a couple hours after work for a few days. probably could do it in a couple days full time if you have the time

[@TheRealKRUE]

What was the total hours spent?

[@ChefOutdoors]

A lot😂 it was done on days off and after work. The time in and out if Everything is perfect could be done in a day. However it never goes that way. Missing parts, needing new parts. All kinds of obstacles. Like opening a can of worms. Once it’s apart you need to fix it all. Ended up being quite a few days total.

U missed the point of the video - how you pulled the engine
